I notice on the website that Lowell is calling this a 'prototype' model. Is this new tooling? I pulled out one of my Walthers coaches (I don't have any since he bought the line from them- is his production different than the Walthers originals?) and the photos he has up on is website of the B&O prototype cars are certainly similar, but not an exact match in terms of window size/locations. Of course, sometimes such things change over the life of a car. I'm just curious if the model is truly 'prototype' or if perhaps a new paint job on the NYC car.
